I believe everything I mentioned as being revolutionary qualifies as being revolutionary.

 

Single board computers like Raspberry Pi are good examples to me.

 

A lot of revolutionary change is in the software realm, rather than hardware.

Google Maps is revolutionary, to my thinking.

 

Gallium nitride transistors, for example are not going to replace most transistors.

nope, but it will allow 60 to 100GHz processors with reasonable efficiency. I'd say the step up from 5 to 60 is pretty revolutionary. I'm just waiting to see what type of real-time augmented reality is possible.

Google Maps is revolutionary, to my thinking.

When the whole world stopped folding paper maps in a few years time. Paper (papyrus) maps have been around since Ancient Greece.

 

Then you would make a great marketing manager.

Google Maps is revolutionary, to my thinking.

Absolutely. But already overshadowed by GPS.

 

One rather less likely to gain headline space or prompt people to invest wildly in startups, but certainly a fundamental change in directions is the change to using a standard USB connection for power and charging. Look at a stack of older cell phones, and see that every one uses a different connector for charging, usually at some different voltage. Previously the goal was to assure that the user had to purchase the $90 OEM charger. Then all at once charging is one connector type, albeit with three different sizes but still one voltage and polarity. THAT IS REVOLUTIONARY!
So the individual claiming nothing "revolutionary" must have had their face buried deeply in a video game for a lot of years.

The revolution in software came from microsopht, discovering that quality is no longer a requirement.

 

The "revolution" of cloud computing - I feel like I'm back in the days of my dumb terminal and everything was on the server.

 

Video moved from analog to digital, CRT moved to LCD and others.
I have a TV/computer monitor that is 1 inch thick, gets information from the air or wire (internet), has very high resolution.
